Overview of the RNA–seq data of SH peach fruit stored at room temperature or low temperatures. (A) Principal component analysis (PCA) of stony hard (SH) peach fruit during harvest, cold storage, and subsequent ripening. Abbreviations used are as follows: CK0, stored at room temperature for 0 d; L1, stored at 4 °C for 20 d; and L2, stored at 4 °C for 40 d; (B) Venn diagrams of DEGs among the different comparison groups (L2 vs CK0, L1 vs CK0, and L2 vs L1); (C) Number of DEGs identified by pairwise comparison in the different comparison groups (L2 vs CK0, L1 vs CK0, and L2 vs L1). Up, upregulation; Down, downregulation. Threshold: |Log2FC| ≥ 2, p < 0.05; (D) KEGG enrichment analysis of 2914 DEGs; (E) KEGG enrichment analysis of 783 DEGs.
